Short on space
ConsiderA 20" cartridge is about double the length of a 10" one, so check there is room below the housing to change it.

Common questions
Is the Essence Plus I right for my home?
It's made for larger New Zealand homes on town (mains) water where chlorine taste and odour is the main concern. For a smaller home or lighter use, the Essence I (10") covers the same job in a more compact format. On rainwater or bore water, a different system will suit you better.
How often do I change the cartridge?
Every 6–12 months, depending on your water quality and how much you use. The larger 20" format usually lasts longer than a 10" system in the same conditions. The Essence Plus I replacement kit has a new cartridge.
What's the difference between the Essence Plus I and Essence Plus II?
The Essence Plus II adds a 1 micron polyspun sediment filter before the carbon block. If your supply has visible sediment, rust flakes or grit, it protects the carbon block and helps it last longer. If your water is clean and taste and odour is your only concern, the Essence Plus I is enough.
How do I know the carbon block needs replacing?
Chlorine taste or smell coming back is the clearest sign, even if flow is still good.
Will it affect my water pressure?
The 20" Jumbo housing is designed to keep good pressure. Keep cartridge changed on schedule. A clogged cartridge is the most common cause of pressure drop.

The Waiora Essence Plus I, made by Waimana, is a single-stage whole-house filter for treated town water. It's built to reduce chlorine taste and odour, using 20" jumbo housing built for higher flow and busier households.
It uses one 5 µm carbon block cartridge. The housing sits on a powder-coated steel bracket with 25 mm BSP stainless threaded ports, and a housing spanner is included. We recommend up to 85 psi (6 bar), with 125 psi (8.5 bar) as the maximum.
Change the cartridge every 6–12 months. 3-year manufacturer's warranty on the housing.
We're NZ owned in Te Rapa, Hamilton. If it's not right, we'll put it right.
